Liquid electroslag remelting device and smelting process

The liquid electroslag remelting device comprises a heating electrode with a supporting arm, the heating electrode is a hollow cylindrical piece, the upper portion of a hollow inner cavity is a conical cavity, the lower portion of the hollow inner cavity is a cylindrical cavity, a flow guide pipe is arranged in the conical cavity in a sleeved mode, the upper portion of the flow guide pipe is a step, and a cone matched with the conical body of the heating electrode is arranged below the step. The flow guide pipe is embedded in a central hole of the heating electrode, and the lower end of the flow guide pipe is higher than the lower end of the heating electrode; a crystallizer is arranged below the heating electrode; after entering the station, the crystallizer does not move up and down in the vertical direction and rotates along the axis in the horizontal direction, molten steel smelted in the early stage is transferred to a tundish through a steel ladle and injected into the crystallizer through a flow guide
